阿伏加德罗常数是摩尔的基准,它的本质是指12g12C所含有的碳原子数,通常用NA表示。通过阿伏加德罗常数可以将物质的质量、气体的体积、物质的量等物理量与微粒数联系起来,在科研、生产中的使用非常广泛,因此阿伏加德罗常数及其应用一直是
The Avogadro’s constant is a reference for the mole, and its essence refers to the number of carbon atoms contained in 12g12C, usually expressed as NA. Through the Avogadro constant, physical quantities such as the mass of a substance, the volume of a gas, the amount of a substance, and the like can be related to the number of particles. The use of Avogadro’s constants and its applications has been widely used in scientific research and production.
